A power transporter is a transportation system that uses non-human energy, such as electricity, wind, or water power. It typically consists of a belt wound around rollers, some of which are connected to a motor. The belts are made of composite materials and the rollers are either idle or active with a textured outer surface for better grip. When not using a belt, the work surface consists of closely spaced rollers, some of which are powered for extra force.
A power transporter is the name of a transportation system that uses non-human energy to operate. Typically, these systems are belts running on wheels powered by electricity, but this is not always the case. Some systems use non-electrical energy, such as wind or water power, while other conveyors use rollers rather than belts. In a typical belt system, the conveyor belt is wound around a set of roller wheels, one of which is driven by an external system. This roller moves the ribbon and the other rollers are for media only.
The idea behind an electric conveyor is very simple. A flat ribbon is made into a ring shape and placed on a series of rollers, which support the ribbon and allow it to maintain a constant shape. One or more rollers are connected to a power source, usually a motor. The motor turns one or more rollers, which causes the tape to move. Users can then place items on one end of the belt and the motion will move the material to the other end.
The belts of a typical electric conveyor are made of a composite material that is custom designed for the conditions in which the belt will operate. Generally, the base of the belt is a strong but flexible material. In the past, this was typically a burlap cloth, but more recent belts use a wide range of natural and man-made materials. This core is then covered in several protective layers to prevent damage that could disturb the tape’s operation. Finally, an outer coating, often made of rubber, gives the belt traction against the rollers and prevents moving objects from slipping.
The rollers used by an electric conveyor are also quite simple. There are two types of rollers: idle rollers, which consist of a metal rod surrounded by a free-moving metal drum, and active rollers, which look the same but the drum is connected to the rod. The outer surface of the drum is textured or glued with a material that will provide a better grip, and it is this outer area that is in direct contact with the belt. Active reels are connected to a power source and inactive reels are not.
When an electric conveyor isn’t using a belt, the work surface is usually just a series of closely spaced rollers. These rollers are all powered, in which case their surfaces have a heavy grip, or only some are motorized, so with only one grip surface and the rest are very smooth. The grip on the active rollers allows them to push work items with extra force along the relatively smooth idler rollers.
